There’s nothing quite like MATA, which every year organizes the city’s most exciting showcase for outstanding young composers from around the world; many intriguing discoveries can be made. This year’s enticements include a piano-bass-percussion trio called Bearthoven, signal contributions from the lauded Momenta Quartet and Talea Ensemble, and an installation in which dozens of table lamps outfitted with transducers make their own weird music. The composers include Eric Nathan (U.S.), Idin Samimi Mofakham (Iran), Ofir Klemperer (Israel), and Ann Cleare (Ireland), among others. (The Kitchen, 512 W. 19th St. 212-255-5793. April 14-18 at 8.)
